Struct SdeLikelihoodCache 

pub struct SdeLikelihoodCache(/* private fields */);

Cache for SDE likelihood values.

SDEs do not produce subject predictions that can be cached, but the likelihood values for a given subject and parameters can still be cached.

Note that the use of a cache could be counterproductive for SDEs, as this removes the stochastic nature of the likelihood evaluation. However, it can be useful for producing a deterministic likelihood for an otherwise stochastic process.

Clone produces a shallow clone that shares the same underlying cache data.

Implementations

impl SdeLikelihoodCache

pub fn new(size: u64) -> SdeLikelihoodCache

Create a new SDE likelihood cache with the given maximum number of entries.

pub fn get(&self, key: &(u64, u64, u64)) -> Option<f64>

Look up a cached likelihood value.

pub fn insert(&self, key: (u64, u64, u64), value: f64)

Insert a likelihood value into the cache.

pub fn invalidate_all(&self)

Remove all entries from the cache.

pub fn entry_count(&self) -> u64

Return the number of entries currently in the cache.
